v1 Claim. (01. 128239) This invention relates to syringes especially with a bead 12. A part of the function of this adapted for veterinary use. head is to act as a stop for the forward move- The main object of the invention is to provide ment of the piston so that when the piston is a device of this kind having means to penetrate moved forward it will come in contact with said 5 the part of the anatomy of the animal desired bead, and the piston being made of soft leather 5 to be treated, and vacuum means to properly will stop withoutajar. position the wall of the anatomy so the interior The interior of the element 3 is provided with thereof can be cleansed in the most efficient mana longitudinal bore 13 which matches up with ner. the bore of the stem. The bore 13 is enlarged at Another object of the invention is to provide the front as at 14 and in the, interior thereof isa I! a rectal front end in the shape of an arrow head ball valve 15. Screwed into the tip of the e1e.--. to penetrate the anatomy of the animal, a ment 3 is a shortnipple 16 having a bore 17 on vacuum cup adapted to distend the wall thereof, line with the bore 13. Numeral 18 designates a and means to pump a fluid in the interior of the pin passing through the nipple and adapted. to

Other objects of the invention will appear as The operation of the device is as follows: The the disclosure progresses. The drawing is inspear headed rectal nozzle'3 is moved forward tended to merely indicate a possible embodiment of the cup 1 as indicated in Figure 1 and inserted of the invention. It is obvious that the actual in the cavity of the animal to be treated so that 20 needs of manufacture may necessitate certain the fleshy part of the anus may slip over the so mechanical changes. It is therefore not intended enlargement of the rectal nozzle and into the.
